Vectorworks, Inc Employee Luis M Ruiz Posted April 29 Vectorworks, Inc Employee Share Posted April 29 Ok my friends. I feel like I had it with the three fingers and five legs. I decided to dig deeper on this issue and made a collection of key words that are great for removing some unwanted visual effects. These work great depending on the image, so give these a try as you need them. I have the feeling this is list that will keep growing. Worst Quality, Low Quality, Poorly Made Bad 3D, Lousy Bad Realistic, ugly, tiling, poorly drawn hands, poorly drawn feet, poorly drawn face, out of frame, extra limbs, disfigured, deformed, body out of frame, blurry, bad anatomy, blurred, watermark, grainy, signature, cut off, draft, deformed bows, missing ear, error, Polydactyly, missing digits, extra digits, simple background, blank background, abstract background, Easy Negative, bad-hands-5, bad and mutated hands, bad hands, missing fingers, multiple limbs, interlocked fingers, ugly fingers, extra digit and hands and fingers and legs and arms, crown braid, deformed fingers, long fingers, comic, muscles, sinewy, bad anatomy, signature, monochrome, text, watermark, duplicate, bad-artist-anime, mature 4 Quote Link to comment

James Russell Posted May 1 Share Posted May 1 (edited) I personally think that using generic bulk negative prompts is problematic when working with text to image machine learning models. I've seen a lot of people these days who just leave their negative prompt as "bad anatomy, deformed hands, deformed face, ugly hair", eventually filling their prompt cap with such phrases. The biggest issue with this is how the machine learning treats the assessment of the negative phrases. For example "deformed hands" although it will overall reduce the finger deformity in hands, it will also generate images which have far less emphasis on "hands" overall, leading to people with their arms behind backs or out of frame. A better case would be to, when refining the image, use positive phrases like "detailed hands" or "detailed hair" which steers the model towards a positive and detailed emphasis on these phrases. If you've looked at a few of my previous posts on the topic of the current implementation of Stable Diffusion into VW2024 the above methodology, and prompts in general, can only go hand-in-hand with better control over the Stable Diffusion Generation - including primarily the Sampling Steps (crucial for a prompt like "detailed hair" as sampling steps <20 won't even get to hair detailing) and InPainting (the process of masking just an area of an image for generative change - for example you could mask just the hand of a person and then run 20 Batched Images over just those hands at a low "Creativity" / CFG and choose the best fit). Stable Diffusion (Same engine as VW, Automatic1111 Interface) Below is an example of a generated human on the right (text to image creation), and then shown on the left is the InPainting region (black) - noting this is Stable Diffusion XL in the Automatic1111 container. The goal of this example is to show the ease in which InPainting can correct fingers (or other elements). (Left: InPainting Mask, Right: Chosen Iteration of Human Figure) The video below shows 50 example hand replacements. Each generation took around 7 seconds on a local machine to make. Hands Example.mp4 50 Images created in 1 Batch for hand replacement, 40 Sample Steps with 7 CFG, 0.4 Denoising Strength (Creativity). Overall, in my experience, prompts (both positive and negative) should be applied on a per image / intention basis, as starting with a bulk prompt eliminates huge portions of the dataset overall. Or as @Luis M Ruiz rightly stated; On 4/30/2024 at 2:50 AM, Luis M Ruiz said: so give these a try as you need them Edited May 1 by James Russell Spelling. 3 Quote Link to comment
Vectorworks, Inc Employee Luis M Ruiz Posted May 15 Author Vectorworks, Inc Employee Share Posted May 15 I ran into this list created automatically in another AI app. I figured I'd add them to the list I am compiling but can also save these here. Remember, experimentation is key! Try different negative prompts to see what works best for your desired outcome. Ugly face, incorrect body proportions. bad drawing, bad anatomy, bad body shape, blurred details, awkward poses, incorrect shadows, unrealistic expressions, lack of texture, poor composition, text, logo, out of aspect ratio, body not fully visible, ugly, defects, noise, fuzzy, oversaturated, soft, blurry, out of focus, frame. 1 Quote Link to comment

zoomer Posted May 15 Share Posted May 15 (edited) Great Link. But .... Quote "Now, let’s understand why negative prompts play a crucial role in stable diffusion. These prompts are essential in the image generation process, ensuring stable diffusion, realistic proportions, and high-quality images." Quote 1st negative prompt “ extra arms, extra legs, extra fingers, extra limbs,bad anatomy, bad proportions, blurry, cloned face, cropped, deformed, dehydrated, disfigured, duplicate, error, gross proportions, jpeg artifacts, long neck, low quality, low-res, malformed limbs, missing arms, missing legs, morbid, mutated hands, mutation,text, signature, ugly, username, watermark, poorly drawn hands, worst quality. ” 2nd negative prompt: “worst quality, normal quality, low quality, low res, blurry, text, watermark, logo, banner, extra digits, cropped, jpeg artifacts, signature, username, error, sketch ,duplicate, ugly, monochrome, horror, geometry, mutation, disgusting” I really would have expected that the AI does this itself automatically, if not specifically wished for in positive prompts !? Or does the target group prefer to get all those negative things mentioned in the negative prompt examples in their results ? Edited May 15 by zoomer Quote Link to comment
Vectorworks, Inc Employee Luis M Ruiz Posted May 15 Author Vectorworks, Inc Employee Share Posted May 15 I have encountered some AI apps that do include the negative prompts and many others show their field blank like the current AI Visualizer. Suggestion taken. Quote Link to comment
James Russell Posted May 15 Share Posted May 15 (edited) @zoomer negative prompts have an equal weighting as positive prompts; and as such we need to be super careful with blanketed negative prompting. For example the terms 'gross proportions' and 'ugly' are not terms which should be baked into the negative steering of a Model or Checkpoint. Imagine you're doing a Tim Burton, Guillermo del Toro or Wes Anderson inspired piece, the characters and theme you're aiming for are inherently 'grossly proportioned' and, to some, 'ugly'. I agree with @Luis M Ruiz that suggesting these prompts, for the most part, is helpful for those learning AI Visualisation and as GUI feature overall - however I would not like to see these baked into the Model or Checkpoint in any way as I think it would immediately set a Model Bias which would limit creativity.

zoomer Posted May 17 Share Posted May 17 “ extra arms, extra legs, extra fingers, extra limbs,bad anatomy, bad proportions, blurry, deformed, dehydrated, disfigured, duplicate, error, gross proportions, jpeg artifacts, long neck, low quality, low-res, malformed limbs, missing arms, missing legs, morbid, mutated hands, mutation,text, signature, ugly, username, watermark, poorly drawn hands, worst quality, worst quality, normal quality, low quality, low res, blurry, text, watermark, logo, banner, extra digits, cropped, jpeg artifacts, signature, username, error, sketch ,duplicate, ugly, monochrome, horror, geometry, mutation, disgusting” I just still think such results as most of these negative prompts should not be likely as a result by default, but something you may add as positive prompts if you like to have it for some reason. I mean the target group loving "jpeg artifacts" or such things in their results may be pretty small. So an AI like in VW is more kind of "unbiased" (?) I think I would have expected something more biased to standard human expectations. For me that sounds like ask ChatGPT for a report and need to add negative prompts for most basic things like don't use bad grammar or avoid typos ..... Quote Link to comment
Matt Overton Posted May 22 Share Posted May 22 Is there a standard prompt that will isolate the "subject" from the background like an image that would be then useful for image props? Negative prompt - Background also variations of the positive prompt "remove background" have no effect. Quote Link to comment
Pat Stanford Posted May 22 Share Posted May 22 A positive prompt of "Over a plain white background" should get your something relatively easy to crop the background from. Quote Link to comment
Pat Stanford Posted May 22 Share Posted May 22 Positive Prompt: Image of a single isolated red rose bush on a solid white background. Photorealistic image. flat solid color background Negative Prompt: background lighting Creativity:49 1 Quote Link to comment
Matt Overton Posted May 22 Share Posted May 22 Yes, that does get much closer. The engine has interesting ideas about cricket. Prompt "group of highschool students playing cricket over a solid white background. " Quote Link to comment
hollister design Studio Posted July 11 Share Posted July 11 Should negative prompts contain the negative? ie "no bright colors" or "bright colors" Quote Link to comment
James Russell Posted July 15 Share Posted July 15 In Stable Diffusion, negative prompts are used to guide the model away from generating certain elements in the image. The prompt should describe the unwanted elements directly without using negations like “no.” When crafting a negative prompt, you should directly describe the elements you want to avoid. For your example, if you don’t want an image with bright colors, the negative prompt should be “bright colors” as the element to avoid. Note: It feels horrible for me as an Australian to use Colors over Colours however slightly more of the SD datasets acknowledge American English... As a more detailed example if your objective was to make; an image of a cozy vintage cafe with wooden furniture, dim lighting, and a warm atmosphere AND to avoid any modern elements, bright colors, and people. Positive Prompt Input Field: “A cozy vintage cafe with wooden furniture, dim lighting, and a warm, inviting atmosphere. The cafe has antique decorations, old bookshelves, and (a small fireplace).” *Note: In the examples below the (a small fireplace) was incremented for the second image as another test. Negative Prompt Input Field: “Bright colors, modern elements, people, electronic devices, neon signs, plastic furniture” Happy generating! J 4 Quote Link to comment
